What do you like best?
It is easy to administer, create accounts, configure email connections, the connection via web http and activate sync by tablet and cell phones is an excellent tool, and easy to set them.
What do you dislike?
it is not so easy to install from scratch, you have to do many steps and look for errors online, at least until the 2010 version. I have not installed the most recent one.
Recommendations to others considering the product
previously note the expansion capabilities when buying the standard version and enterprice, by the number of databases for the mailboxes, the standard manages 4 databases nothing else, and the other is to take into account the width of band for the maximum output capacity of the emails, if you put it too high it can take up a lot of disk space, and collapse the IO.
What business problems are you solving with the product? What benefits have you realized?
have a personalized mail server with independent reception capabilities, and if I do not receive an email because of its weight, I can increase the ability to enter easily, and then re-adjust it as it was. if you have a limit of 15mb by mail for all mailboxes, you can increase it to 30mg and that's it, which you can not do with a public one.
